IMPROVEMENT IN RAlLWAV-TRACK BROOMS.

Specification forming part of Letters Patent No. 180,7 17', dated August8, 1876; application filed Jline s, 1876. t r

To all whom it may concern v Be it known that I, MARCUS O. ISAAOS, ot'

Illinois-,have invented a new and useful Im provement in Railway-TrackBrooms, which is reference being bad to the accompanying Figure l is aperspective view, showing the brushes applied to the track; Fig. 2, aplan view of the brush with the upper portion of the head removed; andFig. 3, a cross-section taken on the line we, Fig. 2, with the headentire.

Herctofore brushes for cleaning railwaytracks have been made with abroom of even face-that is, the brush of the broom, of whatever materialmade, has been of uniform length.

It is obvious that with a brush of such construction the snow or mudbelow the surface of the track-rail will not be removed to any greatextent. 1!; is. however, desirable that should be brushed away below thesurface of. the rail, so as to leave no obstructions to the flanges ofthe wheels, which are upon the inside of the rails.

The object of my invention is to provide a broom which will sweep notonly the surface of the track-rail, but will also remove material uponthe inside of the rail some distance below the surface thereof.

The invention consists in making the brush of the broom with an unevensurface, or, in other words, with-one portion of the brush longer thanthe other, so that it will extend below the surface of the rail whenapplied thereto for the purpose of cleaning the track.

In the drawings, A A represent the rails track-brooms, which areattached to the 10- comotive, or in street railways to one of the cars.

The brush portion of the broom maybe divided into two sections, onesection, a, being shorter than the other, b, so that the face of thebrush is uneven, as clearly shown in Fig. 3 of the drawings. i I

The brush is constructed so that these sections are divided laterally,and when applied to the rails the shorter section is placed I the longersection of the brush will extend one side thereof, as shown in Fig.1 ofthe drawings. 7 I

It is evident that when applied in this way, not only will the surfaceof the rail be cleaned by the short section of the brush, but the longsection, extending below the rail-surface, will clean out a channel atthe side of the rail. As it is desirable to clean this channel upon theinside of the rails so wheels, the brooms are applied with the longsections of the brush inside of the rails, as shown in Fig. 1; but, ifdesired for any purpose-whatever, theyinay be applied equally as well asupon the outside of the rails, or a long brush-sectioumay be made toextend on both sides of the rails, leaving ashort central section torest upon the rail-surface. V

The broom may be made of any suitable material, although I prefer wire.The material of the brush is fastened to the lower portion 0 of the headin the usual way, by doubling it and thrusting it down through holes inthe block O, the loops being caught shown in Fig. 2 of the drawings. Theupper blockl) of the head is then secured to the lower block 0 by meansof screws, or in any other suitable manner.

I do not limit my invention to any particular method of fastening thebrush to the head, as my invention is applicable to brooms of anymaterial, and to any kind of a fasten- -The material herein mentionedand the mode of fastening herein described, are not claimed by me as ofmy in ention, for both have been known and used heretofore.

- Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- i A railway-track broom, constructed witha brush of uneven facethat is, with one portion of the brush longerthanthe other, substant-ially as and for the purpose set forth.
